Unnderstanding Longitude & Latitude. Typical Graph. This is an example of a typical graph we are all familiar with. The graph is made up of different “points” with lines that connect the points. Typical Graph. Y axis. Each point has two values:
Longitude & Latitude
latitude lines run horizontally. Latitude lines are also known as parallels and are an equal distance from each other. Degrees latitude are numbered from 0° to 90° north and south. Zero degrees is the equator, the imaginary line which divides our planet into the northern and southern hemispheres. 90° north is the North Pole and 90° south is the South Pole.
The vertical longitude lines converge at the poles and are widest at the equator (about 69 miles or 111 km apart). Zero degrees longitude known as the Prime Meridian is located at Greenwich, England (0°). The degrees continue 180° east and 180° west where they meet and form the International Date Line in the Pacific Ocean.
If you said South and East , you’re right!
This is also true of longitude.
Latitude: (90oN to 90oS)
Longitude: (180oE to 180oW)
Tropic of Cancer
Latitude 23½o North
Tropic of Capricorn
Latitude 23½o South
Longitude 90o West
Longitude 60o West
Longitude 60o East
Longitude 30o West
Longitude 30o East
Positioning on the Earth’s Surface
Latitude and Longitude together enable the fixing of position on the Earth’s surface.
The tropics are the two lines where the sun is directly overhead at noon on the two solstices . The sun is directly overhead at noon on the Tropic of Cancer 23.50 N on June 21 and the sun is directly overhead at noon on the Tropic of Capricorn 23.50 S on December 21
The area between the Tropic of Cancer and Tropic of Capricorn is known as the "tropics." This area does not experience seasons because the sun is always high in the sky.
Notes Page Time ZonesWhy do we need them? When it is dark and the middle of the night where you are, at some other place it is the early morning, somewhere else it is lunch time. Don't you think it would be pretty confusing to have it called "midnight" in all those places?
If it is 4:00 PM in New York What time will it be in Iowa, Utah, and Oregon?
